Nippon Kayaku NK poleve semiconductor resist strippers
Nippon Kayaku Co., Ltd. · Material properties and interface engineering
- Purpose
- Post-plasma-dicing cleanup needs resist, etch residue and sidewall damage distinguished.
- Technical approach
- NK poleve semiconductor strippers include standard grade 517 and grade 496 for hardened Bosch/TSV resist.
- Scope of use
- Consider resist-removal needs; confirm post-dicing residue and exposed metal/dielectric compatibility.
- Limitations and open questions
These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitationsThe page does not establish compatibility with a specific plasma-dicing process, zero residue/corrosion or silicon-damage repair. An unnamed post-ashing example cannot be assigned to 517/496.
What to prepareBLNKK suggests preparing resist/plasma history, residue analysis, sidewall/metal/dielectric details and before/after imaging and electrical observations.
Confirm with the supplierConfirm grade selection, target-residue removal, soak/rinse/dry conditions and assessment of corrosion, surface changes and subsequent bonding compatibility.
- Public evidence
- The official semiconductor section distinguishes 517/496 and describes WLP resist and post-ashing residue-cleaning uses.
